Subject [jira] [Commented] (HADOOP-6994) Api to get delegation token in AbstractFileSystem
Date Tue, 12 Apr 2011 20:00:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13019011#comment-13019011
] 

Jitendra Nath Pandey commented on HADOOP-6994:
----------------------------------------------

The latest patch fixes FilterFileSystem and FilterFS. The renew and cancel delegation token
APIs are removed from the patch. These APIs should be implemented as a util methods in SecurityUtil
and the filesystem to renew or cancel can be figured out from the service and kind set in
the token itself. Implementation in SecurityUtil will be taken up in a separate jira.

> APIs to get delegation tokens is required in AbstractFileSystem. AbstractFileSystems
are accessed via file context therefore an API to get list of AbstractFileSystems accessed
in a path is also needed. 
> A path may refer to several file systems and delegation tokens could be needed for many
of them for a client to be able to successfully access the path.
